Hi Pilou, yes that's normal and intentional - the perp/perp snap will only engage if the initial pick point was within 65 pixels (actually 4 times the object snap radius) of the actual perp/perp location.

That helps to keep perp/perp to only engage when you pick somewhere in the general area of the perpendicular line, otherwise it was kind of weird when the base point would suddenly fly off to some far away location from your picks.

Hi Michael,

When I do Relocate cline I see on object "On", "Int", "Cen", "End" etc. and intuitively expect "Perp/On" and "Tan/On".

Hi Brash, the "On" osnap is so generic it is intentionally not combined with other object snap labels if a "specific point" one is active.

That's because otherwise you would be seeing it added to every single label except "Cen", because they are all points on the curve.

So since that would be a lot of extra labeling that would be nearly always present, "On" is only displayed when there is not any more specific snap engaged.
